The category of laptop/tablet hybrids is one of the favorites among Windows PC manufacturers, including the Japan-based Panasonic. Accordingly, the Toughbook maker hosted a conference in the Land of the Rising Sun recently, where it took the time to reveal its new CF-MX3 convertible laptop. This adjustable machine comes with a 12.5-inch, 1,920 x 1,080 LCD, a removable battery that can last between 14 to 15 hours, Windows 8.1, pen support and a built-in DVD drive -- yes, a DVD drive. The entry-level CF-MX3 features a 2.6GHz Core i5-4200U CPU, 4GB RAM and a 128GB SSD, while there's also an option with double the memory and storage, a 3.0GHz Core i7-4500U CPU and a Pro version of Microsoft's OS. Furthermore, Panasonic loaded the MX3 with a ton of ports, such as two USB 3.0, HDMI, VGA and an SD card reader; all in all, it weighs in at roughly 2.65 pounds. Pricing details for Panasonic's CF-MX3 convertible are still unknown, though we do know it'll be available in Japan starting February 14th.
